Quasar, - Vielzahl

Durch Reibung heizt sich diese Scheibe auf, wobei gleichzeitig Teile der Materie Drehimpuls verlieren und so in das Schwarze Loch fallen können. One strong argument against them was that they implied energies that were far in excess of known energy conversion processes, including nuclear fusion. Quasars are believed to be powered by accretion of material into supermassive black holes in the nuclei of distant galaxies, making these luminous versions of the general class of objects known as active galaxies. Several dozen nearby large galaxies, with no sign of a quasar nucleus, have been shown to contain a similar central black hole in their nuclei, so it is thought that all large galaxies have one, but only a small fraction are active with enough accretion to power radiation and so are seen as quasars. The term "quasar" originated as a contraction of "quasi-stellar radio source", because quasars were first identified as sources of radio-wave emission, and in photographic images at visible wavelengths they resembled point-like stars.

Since quasars exhibit properties common to all active galaxies , the emission from quasars can be readily compared to those of smaller active galaxies powered by smaller supermassive black holes. Sie sahen aus wie ein Lichtpunkt, der nicht mit Teleskopen aufgelöst werden konnte. High-resolution images of quasars, particularly from the Hubble Space Telescope , have demonstrated that quasars occur in the centers of galaxies, and that some quasar host galaxies are strongly interacting or merging galaxies.
